Switch 3850，noted：PLATFORM_PBR-3-UNSUPPORTED_RMAP: Route-map CE11 has unsupported options for Policy-Based Routing. It has been removed from interface, if applied.

Hi，

We have a switch 3850，and we wanted to configure a route-map on the interface and vlan，but when we enter the commond ‘ip policy route-map CE11’ under the interface vlan ，it noted a console error：

PLATFORM_PBR-3-UNSUPPORTED_RMAP: Route-map CE11 has unsupported options for Policy-Based Routing. It has been removed from interface, if applied.

then，show runn，we didn't find this commond： ip policy route-map CE11 under the interface

Here are some my related configuration

ip sla 20
icmp-echo 10.58.1.22 source-interface Vlan24
threshold 3
timeout 1000
frequency 3
ip sla schedule 20 life forever start-time now

track 20 ip sla 20 reachability

ip access-list extended CE11

 deny ip host 1.1.1.1 host 2.2.2.2

 permit ip host 1.1.1.1 any

route-map CE11 permit 10
match ip address CE11
set ip next-hop verify-availability 10.62.24.3 1 track 20

And when we configure on the Switch 4507，it didn't note the error information

Does anyone know why it is？

We want to modify some traffic's next hop only the remote site can be reached，and use the acl to match the traffic.When

the remote site can't be reached, don't modify these traffic's next hop and make them use the default route :ip route 0.0.0.0 0.0.0.0 10.62.24.2

If the route-map can't used under the interface in 3850, please tell me what else can meet the above requirements

Hello,

the 'verify-availability' command with IP SLA itracking s not supported on the 3850. Not knowing your exact configuration, you could use EEM as a workaround:

event manager applet VLAN_24_UP
event syslog pattern "%TRACKING-5-STATE: 20 ip sla 20 reachability Down->Up"
action 1.0 cli command "enable"
action 2.0 cli command "config t"
action 3.0 cli command "interface Vlan24"
action 4.0 cli command "ip policy route-map CE11"
action 5.0 cli command "exit"
action 6.0 cli command "end"
!
event manager applet VLAN_24_DOWN
event syslog pattern "%TRACKING-5-STATE: 20 ip sla 20 reachability Up->Down"
action 1.0 cli command "enable"
action 2.0 cli command "config t"
action 3.0 cli command "interface Vlan24"
action 4.0 cli command "no ip policy route-map CE11"
action 5.0 cli command "exit"
action 6.0 cli command "end"

Thank you for your advice，I will try to configure the EMM on the 3850.

And I also want to ask why the 3850 can't support the 'verify-availability' command with IP SLA tracking , because of the hardware or the software ？

Hello,

good question. Usually, with unsupported commands and features, it is a combination of hard AND software, as the architecture of switches is different from that of routers. I cannot really tell you why this specific subcommand is not supported...:(

[junlingxiner]

Hello，

I have another question，if the number of the cli command in the EMM has a limitation.

because I need to apply the route-map to four or more interface , so I may need configure a dozen commands in the EMM

For example：

event manager applet SLA_20_UP
event syslog pattern "%TRACKING-5-STATE: 20 ip sla 20 reachability Down->Up"
action 1.0 cli command "enable"
action 2.0 cli command "config t"
action 3.0 cli command "interface Vlan24"
action 4.0 cli command "ip policy route-map CE11"
action 5.0 cli command "exit"
action 6.0 cli command "interface Vlan25"
action 7.0 cli command "ip policy route-map CE11"
action 8.0 cli command "exit"
action 9.0 cli command "interface Vlan26"
action 10.0 cli command "ip policy route-map CE11"
action 11.0 cli command "exit"
action 12.0 cli command "interface G1/0/33"
action 13.0 cli command "ip policy route-map CE11"
action 14.0 cli command "exit"
action 15.0 cli command "end"

Hello,

there is no limit. You can also use numbering such as:

action 1.1

action 1.2

action 1.3

etc...

OK，thank you so much！
